Stochastic Simulation of Daily Rainfall

1975
Abstract: The design of many water resources projects requires knowledge of possible long-term rainfall patterns. In this project a stochastic model based on a first order Markov chain was developed to simulate daily rainfall at a point. The model is applicable to any point in Kentucky (and other areas with similar rainfall patterns).

RAINFALL SIMULATOR FOR LABORATORY STUDIES

Applied Engineering in Agriculture, 2000
Numerous types of rainfall simulators have been used to study the fundamental behavior of sediment transfer and chemical movement in soil from rainfall. For results of these studies to be representative, it is essential that the artificial rainfall have characteristics similar to that of natural rainfall.

Stochastic generation of daily rainfall events: A single-site rainfall model with Copula-based joint simulation of rainfall characteristics and classification and simulation of rainfall patterns

Journal of Hydrology, 2018
Abstract Rainfall event simulation can be very useful in many hydrological and hydraulic practices such as dam design. The aim of this study is to propose a new single-site stochastic model for generating daily rainfall events. The model has two components: Copula-based joint simulation of rainfall characteristics and rainfall temporal pattern ...

Technical report of a rainfall temperature control system for rainfall simulators

CATENA, 2018
Abstract Rainfall Simulators are widely used in studies on soil erosion. Most of the rainfall simulators use water with tap or ambiance temperature. However, previous studies showed that soil erosion may increase or decrease by up to three times while raindrops temperature varied from 2 °C to 20 °C.

Noise of simulated rainfall on roofs

Applied Acoustics, 1990
Abstract New Zealand has problems with noise in buildings caused by rainfall. This is due to high rainfall rates and a lightweight style of building. Experimental and theoretical work has been carried out to examine the effect of various roof constructions on noise transmitted to rooms beneath the roof and to investigate the mechanisms of noise ...

A NEW RAINFALL SIMULATOR FOR USE IN LOW-ENERGY RAINFALL AREAS

Applied Engineering in Agriculture, 1998
A sound assessment of hydrologic and erosional responses in wildland and agricultural ecosystems to rainfall requires that rainfall simulators mimic natural rainfall. The accuracy and usefulness of the assessment improves with increased similarity between natural and simulated rainfall.

Error influence of radar rainfall estimate on rainfall-runoff simulation

Stochastic Environmental Research and Risk Assessment, 2015
Radar systems have been widely employed to measure precipitation and predict flood risks. However, radar as a rainfall measuring device and the produced rainfall estimate contain uncertainties and errors resulting from sources such as mis-calibration, beam blockage, anomalous propagation, and ground clutter.

ELECTRONIC CONTROLS FOR RAINFALL SIMULATORS

Transactions of the ASAE, 1997
Rainfall simulators provide control of natural environmental factors such as rainfall intensity and duration to determine basic information on hydrologic and chemical processes within watersheds. Three electronic controllers were designed to provide a range of solutions to automate rainfall simulators.

A Critique of Methods of Simulating Rainfall

Water Resources Research, 1970
Observations of drop size distributions in natural rainfall have shown that the range of drop sizes increases with increasing rainfall intensity. If a network of nozzles is used to generate artificial rainfall, an increase in working pressure increases the average intensity but decreases the range of drop sizes within the spray.
